DESCRIPTION
The LSX connector module is an LGX compatible, rack-mounted termination panel. It provides
a physical interface between fiber optic cables (terminated on the rear side of the bulkhead) and
patch cords (terminated on the front). In a typical application, cables from transmission
facilities are patched to fiber optic terminal equipment. The LSX connector module may be
used in either an interconnect or cross-connect configuration, in either single mode or
multimode applications, and with either stranded or ribbon cable. The cables may be either
Intrafacility Fiber (IFC) or Outside Plant (OSP).
The LSX connector module is available in three chassis heights: 7-inch, 9-inch, and 10-inch.
The 7-inch chassis can be ordered with either 72 or 96 fiber termination positions. The 9-inch
chassis has 144 positions. The 10-inch chassis has 216 positions. In addition, the 7-inch, 72
position module can be ordered in a double stack configuration providing 144 positions or in a
triple stack configuration providing 216 positions; the 9-inch module can be ordered in a triple
stack configuration providing 432 positions.
Figure 1 and Figure 2 show the main external features of the 7-inch, 72 position module and the
9-inch, 144 position module, respectively.

Installing a Cable Clamp
After the cable has been prepared as described, a cable clamp can be installed using the
following procedure. For names of cable clamp components, refer to Figure 13 for the 7-inch
module and Figure 14 for the 9-inch module.
Note: Figure 13 and Figure 14 show the cable clamp bracket positioned for cable routing
from above the module with the bracket fastened using the two upper mounting holes in
the cable mount plate. For cable routing from below the module, turn the cable clamp
bracket upside down compared to how it is shown in the figure and use the two lower
mounting holes in the cable mount plate.
1. Install the cable clamp bracket on the clamp mount plate using two #12-24 screws. Be sure
to position the cable clamp bracket corresponding to the note above.

CABLE ROUTING AND REPLACEMENT
After preparing and clamping the cable as described in Section 4, above, you can route the cable
fibers into the rear of the LSX module. For instructions, refer to the separate procedures below
for stranded cable, ribbon cable, and quad cable. This section also contain instructions for
replacing one or more cable fibers if necessary. Separate procedures are provided for a single
fiber and quad cable.

Routing Stranded Cable
If a stranded cable is being installed, route the cable fibers into the rear of the LSX connector
module using the following procedure (see Figure 17).
1. Position the cable breakout an inch (2.54 cm) after the cable clamp.
2. Route the subunits to the front center retainer, as shown, with the subunits broken out into
individual fibers at that location.
3. Route the fibers around the retainers and then fan them out to the adapter ports, as shown
in Figure 17.

Routing Quad Cable (Two Active Fibers, Two Spare Fibers)
If a quad cable is being installed, route one-half of the quad cable into the left side and the other
half into the right side of the module (as shown in Figure 19). Quad cables entering the module
from the left (when viewed from the rear) are terminated on the right half of the module. Quad
cables entering the module from the right (when viewed from the rear) are terminated on the left
half of the module. Use the following procedure.
1. Terminate each working pair of fibers to the appropriate adapter locations.
2. Route the fibers through the cable retainers in the module to the rear center retainer.
3. Route spare fibers around the retainers and allow them to lie in the bottom of the module.

Replacing a Single Fiber or Fiber Pair Termination
Sometimes it may be necessary to replace a fiber or pair of fibers when equipment upgrades
occur or when a fiber becomes damaged. To do this, use the following procedure.
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the
adapter packs. Exposure to invisible laser radiation may result. An optical power meter should
be used to verify active fibers. A protective cap or hood MUST be immediately placed over any
radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of
radiation exposure. This practice also prevents dirt particles from entering the adapter or
connector.
1. Identify and label the fiber(s) to be removed.
2. Remove the connector from the adapter and place a dust cap on the connector end. Locate
the fiber cable in the module and gently remove it from the cable retainers.
Page 19
© 2003, ADC Telecommunications, Inc.
ADCP-93-089 • Issue 3 • March 2002
3. Determine the new fiber(s) to be terminated and remove it from the spare cable bundle.
4. Route the new fiber(s) through the cable retainers. Remove the dust cap from the
connector and clean the end face of the cable. Install the connector(s) into the appropriate
adapter/connector(s).
5. Route the removed cable to the spare cable bundle and secure it with tie wraps or lace as
required by local practice.
5.5
Replacing a Quad Cable
If replacing a quad cable, first remove the old quad cable using the following procedure.
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the
adapter packs. Exposure to invisible laser radiation may result. An optical power meter should
be used to verify active fibers. A protective cap or hood MUST be immediately placed over any
radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of
radiation exposure. This practice also prevents dirt particles from entering the adapter or
connector.
1. Locate the quad cable to be removed from the cable bundle in the overhead racking.
Follow the cable to the breakout point in the module and verify working and spare fiber
pairs.
2. Using a light source, verify the spare fibers at the equipment locations specified.
Disconnect the working fibers from the equipment and install dust caps.
3. Disconnect the working fiber pair from the adapters, and install dust caps on the connector
ends.
4. Remove the working and spare fibers from the cable retainers. See Figure 19.
5. Cut the strain relief holding the cables in the vertical cable guide but do not remove the
strain relief.
6. Attach the end of a new strain relief to one end of each cut strain relief and use the cut
strain relief to pull in the new relief around the cable bundle.
7. Repeat steps 5 and 6 for each strain relief supporting the cable bundle.
8. Remove the quad cable from the cable bundle.
9. Tighten the new strain relief(s) around the cable bundle.
Page 20

ADCP-93-089 • Issue 3 • March 2002
After removing the old quad cable, perform the following steps to install a new quad cable.
1. Label the ends of the new cable in accordance with local practice.
2. Cut the strain relief holding the cable bundle to the rack but do not remove the strain relief.
3. Attach the end of a new strain relief to one end of each cut strain relief and use the cut
strain relief to pull in the new relief around the cable bundle.
4. Repeat steps 2 and 3 for each strain relief supporting the cable bundle.
5. Insert the quad cable into the cable bundle. Connect the working fibers to the equipment.
6. Route the quad cable through the radius limiters and retainers on the module and separate
the working and spare fiber pairs. See Figure 19.
7. Remove the dust caps from the working fiber pair, clean the end face of the connector, and
attach these fibers to the module connectors.
8. Remove the cable slack from the working and spare fiber pairs on the module and route
the excess into the overhead cable bundle.
9. Tighten the new strain relief(s) around the cable bundle.

PATCH CORD ROUTING
Cross-connect patch cords on the LSX modules and LGX frame must be carefully routed to
ensure they are properly protected. For details, refer to the following topics.
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the
adapter packs. Exposure to invisible laser radiation may result. An optical power meter should
be used to verify active fibers. A protective cap or hood MUST be immediately placed over any
radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of
radiation exposure. This practice also prevents dirt particles from entering the adapter or
connector.
Note: Whenever connecting patch cords, inspect and clean all connectors and adapters
following the cleaning guidelines provided in Section 7.3 on page 33.
6.1
Patch Cord Routing Within the LSX Module
Route patch cords vertically down the front of the connector pack on each module then left or
right through the guides and radius limiters on the LSX module (see Figure 20).

Routing Patch Cords on the LGX Bay
When routing patch cords on the LGX bay, allow for a minimum of 6 in. (152 mm) of slack loop
in the vertical trough. This loop aids in the tracing of patch cords and also facilitates removing a
patch cord from the bundle. Additional fiber slack should be expected when installing a set of
pre-connectorized patch cords. Refer to the following topics for patch cord details for a standalone bay, adjacent bays, and non-adjacent bays.
6.2.1
Cross-Connecting Within a Stand-Alone Bay
Cross-connecting within a stand-alone bay (shown in Figure 21) may be required when facility
and equipment terminations are intermixed Most cross-connection routing within a stand-alone
bay should be done with 5 meter (16.5 ft.) patch cords. Shorter 3 meter (9.9 ft.) patch cords can
be used when both ends are terminated in the top half of the bay.
Use the following procedure to route patch cords on a stand-alone bay:.
Note: Three patch cord examples (A, B, and C) are shown.
1. Loop the patch cord across the upper raceway.
2. Route the right side of the patch cord down through the right vertical trough to the LSX
module where the right side of the patch cord will be terminated.
3. Route the left side of the patch cord down through the left vertical trough to the LSX
module where the left side of the patch cord will be terminated.
Page 22
© 2003, ADC Telecommunications, Inc.
ADCP-93-089 • Issue 3 • March 2002
4. Route the ends of the patch cords inward from the vertical troughs to the respective points
of termination. Connect the two ends of the patch cord at the desired adapters.
Note: On same side terminations, one end of the patch cord will extend across the midline
of the bay (as shown in Figure 21 for patch cords B and C). On opposite side terminations
(patch cord A), the patch cord will not extend across the midline of the bay.
5. Adjust the slack length at both ends of the patch cord to about equal length and dress the
excess length within the jumper retainers.

Cross-Connecting Between Adjacent Bays
Most cross-connection routing between adjacent racks should be done with 6 meter (19.8 ft.)
patch cords. Shorter 4 meter (13.2 ft.) patch cords can be used when both ends are terminated in
the top left of the frame.
To cross-connect between adjacent bays (shown in Figure 22), use the following procedure.

1. Terminate one end of the patch cord on the originating LSX module and bay, then route
the patch cord left or right to the nearest vertical trough.
2. At the destination module and bay, terminate the opposite end of the patch cord, then route
the patch cord left or right to the nearest vertical trough.
3. Loop the patch cord over the upper raceway or jumper support bracket to the adjacent rack.
4. Adjust the slack length at both ends of the patch cord to about equal length and dress the
excess length within the jumper retainers.
6.2.3
Cross-Connecting to Non-Adjacent Bays
Patch cords may be routed through upper or lower raceways to non-adjacent bays in an LGX or
LSX lineup. As a general rule, patch cords originating in LSX modules located in the upper half
of an originating bay are routed to the upper raceway. Conversely, patch cords originating in
modules located in the lower half of an originating bay are routed to the lower raceway.
6.2.3.1
Patch Cord Length Selection
Patch cord length is a concern when cross-connecting to non-adjacent bays because the bays
may be at various distances from one another. To select the correct patch cord length, you must
take into account the number of bays to be traversed and which raceways will be used to route
the patch cord. To select a patch cord based on these factors, refer to Table 2.

Mounting 144-Position Modules Adjacent to 72 or 96 Position Modules
Lucent LGX fiber distribution frames with a depth of 12 inches (30.1 cm) are typically used to
mount LSX 72 position or 96 position connector modules. When mounting 144 position
connector modules, Lucent LGX fiber distribution frames with a depth of 15 inches (38.1 cm)
are recommended to accommodate the greater cable density.
If a 15 inch deep LGX frame is not available, use a rear duct extension kit (Lucent catalog #
FEX1A-FB or equivalent) to extend backward the rear doors of the frame. The new 15 inch
deep frame will line up with any existing 12 inch deep frame as shown in Figure 27. In addition,
the relative mounting locations for Lucent JR4A-1 and JR4C-1 retainer caps, on the front of
adjacent bays containing LSX modules of different heights, will be skewed horizontally as
shown in Figure 28. The degree of retainer misalignment varies with the number of modules
used to populate the adjacent bay.

OPERATION
Removing a Cover for Easier Access
The front and rear covers of the chassis may be removed to provide easier access for cable
routing. To remove a cover, lift it straight out of the hinges. To replace a cover, position the
hinge edge of the cover on the hinges and press inward to push the edge into the hinges.
7.2
Patching and Testing
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the
adapter packs. Exposure to invisible laser radiation may result. An optical power meter should
be used to verify active fibers. A protective cap or hood MUST be immediately placed over any
radiating adapter or optical fiber connector to avoid the potential of dangerous amounts of
radiation exposure. This practice also prevents dirt particles from entering the adapter or
connector.
Testing and patching of optical circuits are done on the front of the LSX module using patch
cords. Whenever patch cords are installed, route them down and to the side, as with crossconnect patch cords. Refer to Figure 30 below; see also Figure 20 on page 22.

7.3
Cleaning Connectors and Adapters
Whenever connecting or disconnecting connectors to an adapter, the connectors and adapters
should be carefully cleaned. Observe the following guidelines:
Page 33
© 2003, ADC Telecommunications, Inc.
ADCP-93-089 • Issue 3 • March 2002
1. Remember that a single connector is one-third of an interconnection system comprised of
two connectors and an adapter: if any one of the three components is dirty, it is likely that
all three components are dirty and must be cleaned. Don't mate a “clean” connector with
another connector whose cleanliness is unknown or suspect. If necessary, disconnect and
inspect an installed connector before installing another (clean) connector. Cleaning the
adapter is often also necessary when it is apparent that two pre-cleaned connectors become
contaminated after installation.
2. Inspect the endface at 200X: adjust the microscope to place the fiber in the upper center of
the field of view and rotate the connector to view a 360° area. Focus on the fiber, and
adjust the illuminator and the monitor contrast and brightness so that particles ON the
endface and ADJACENT the endface are observed (for some inspection systems, this may
involve more than one adjustment at each viewing).
a. If the endface appears to be “very dirty” (liquid-looking droplets, many particles,
smears, etc.), pre-clean the endface with a lint-free laboratory tissue (Kimwipes® EXL or equivalent) or a Fiberclean cartridge cleaner. When using this type of a cleaning
cartridge, use a very light pressure to the non-woven cleaning fabric, apply 2-3 strokes
over the fabric with a slight rotation of the endface, keep the endface surface parallel
to the cleaning fabric (this is especially important on angled connectors!), and DO
NOT reuse any area of the cartridge fabric. When possible, clean the “sides” (outside
diameter) of the ferrule as well as the endface. If available, use alcohol (reagent or
technical grade isopropyl alcohol) with a lint-free tissue: moisten (do not
SATURATE!) several folds of the tissue with a very small amount of alcohol and
firmly rub/twist the alcohol-moistened portion of the tissue onto the connector
endface, then immediately “final polish” the endface per (b) below or with another
folded dry laboratory tissue.
b. If the endface is just “slightly” dirty (a few very small particles), then use a cleaning
cartridge that contains a finely-woven cleaning fabric (the “Reel Cleaner Optical
Connector Cleaner” or equivalent) to provide a spot-free, scratch-free connector
endface. Use a very light pressure to the cleaning fabric, apply 2-3 strokes over the
fabric with a slight rotation of the endface, keep the endface surface parallel to the
cleaning media (this is especially important on angled connectors!), and DO NOT
reuse any area of the cartridge fabric. Folding a lint-free tissue into 4-6 layers and
lightly applying it to the endface will also accomplish this purpose.
c. REJECT any connectors that do not clean up, are scratched (NO defects permitted in
the fiber CORE!), or have many or large pits in the endface ceramic adjacent to the
fiber (within approximately 100 microns or roughly a fiber diameter).
d. Avoid the use of compressed air or “canned gas” to clean non-angled endfaces. If
canned gas is used to clean any components, exercise extreme care not to tip/tilt the
container during its use (liquid material will be ejected and deposited onto the
endface). Low quality compressed air or improper use of canned gas can cause more
endface contamination than it removes.
3. Re-inspect each endface after cleaning.
